TO ALL WHOM IT MAY GONCERN:

Be it known that I, DANI EL GHURoHILmot Ionia, in the county of Warren, and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the lettersof reference marked thereon, like-letters indicating like parts wherever they occur. V I v To enable othersskilled in the art to construct and use my in,vention,'I will proceed to describe it.

My invention consists incertain improvements in the devices for attaching the'plough-benms to the main frame, and in provision fdr adjusting the beams and-ploughs. It also consists incertain improvements in the construction and arrangement of the draught-rods, as hereinafter more fully explained.

Figure 1 is a top plan view.

Figure 2, a rear elevation of frame with the ploughs detached; and

Figures 3, 4, and 5 are views of portionsshown indetail.

I'construct the main frame of two inclined bars, A, united at the top to the tongue B, with a horizontal" bar, G, fastened on each side of the tongue, and extending back of the main frame, diverging as they extend backward,'as represented in fig. 1. .To the lower end of the bars A, I bolta short iron axle, L, mounted upon wheels, as shown. 7 The plough-beams D are constructed in the usual manner, with two shovel-ploughs, E, attached, and also a handle, It, for holding them. On the rear side of the bars. A, I secure a metal plate, J, the form of which is shown in figs. 1, '2, and 3. This plate has, at each corner oiv its horizontal. parts, above and below, a stud, c, projecting vertically, as shown figs- 2 and 6, which serve as pivots on which the beams D are pivoted to turn laterally, as will be hereinafter more fully explained. In the front end of each beam, D, is secured, in a vertical position, a metal plate, I], the form of which is shown in figs. 3 and 4. The front end of this plate is rounded, and has a hole, a, passing laterally through it to recdive abolt, m, as shown in fig. On thesides of'the plate F, where it projects from the front end of the bcamD, and concentric with the hole m, there is formed a lateral projection, a, as shown in fig. 4, and in section in fi-g., 5'. I then provide two metal plates, I, the rear portions of which have, on their inner faces, an annular recess or groove, corresponding in size with the annular projection a on plate F,-and also a hole for. bolt on to pass through. These plates, I, are placed one on each side of theplate F, as shown in fig. 5, and are secured together by the bolt m. The front ends of the plates I are enlarged vertically to a'sizc corresponding with the height of the plates J, and each has, at the-rear corner of this enlarged part, a recess, '2, as represented in fig. 2,-of suitable size, when the two plates I are united to form a socket for the studs 0 on plates J. The hole '16 in plate F is made larger than bolt m, so as to admit loosely the rings n, of which a suflicientnuuiber is placed around the bolt m to prevent the plates Ifrom being pressed together so tightly as to bind on the plate It will thus'be seen-that the plate F is held m place between the plates by the annular projection a fitting in the recess on the inside of the plates -I, and r I does not draw on the bolt m. I

When the parts are thus arranged, the beams are attached to the main frame by fitting the studs c on plates J into the sockets 0 in thei edges of the plates 1- -By means ofthe slots in plates J, the latter, with the beams D, maybe adjusted higher or lower, as maybe required; they may also be inclined,'as represented on the right-hand side of fig 2, by which the beam, with its ploughs, may he turned so as to throw the inner or outer plough deeper into the soil, as maybe desired. :By swinging the ploughs outward, and raising its rear end upward, the ploughs may be detached from the. plated, and changed to the other studs, 0, on the same plate, so as to bring the ploughs closer together, or move them'further apart, to suit different widths of rows. The draught-apparatus consists of two rods, T, pivoted to the front side of the bars A by clips I and d, and having their lower ends bent at right angles laterally, while their upper ends are bent so as to project forward, as represented in fig. 1. At their front upper ends thcse rods T are connected by a cross-rod, H, which has its ends bent to fit in any of, a series of holes in the upper 'ends of the rods T, by which they may be so adjusted as to give to either of the animals an advantage in' the diaught. Near the rear end of each bar, 0, is a hook, upon which the beams may be suspended when the cultivator is being transported from place to place.

Having thus described my invention, what I claim, is-

1. The plates I and F, when constructed and arranged to operate substantially as describecL 2. The plates J, presided with the studs 0, for securing and holding the beams to the main frame, and having also the slots for adjusting them, as set forth. V

3. The combination of the bent rods '1 and. cross-rod -H, pivoted to the main frame; and arranged to operate as described. v
